With an impedance of 8 ohms and an innovative crossover, it delivers natural and clear sound despite the coverage by the ceiling film. Equipped with a 4-inch woofer and a tweeter, as well as integrated bass reflex technology, it impresses even in the bass range with an extremely flat design height of only 58 mm.\u003c\/p\u003e\n\u003cp\u003eThe integrated amplifier offers a power of 2x 5 W, allowing you to conveniently stream music from your smartphone via Bluetooth.

For optimal sound distribution, correct placement is crucial, which can be coordinated with the WHD project planning team. This ensures that the loudspeaker is not only perfectly mounted but also ideally positioned to achieve the best sound experience. The distance between the stretch ceiling and the loudspeaker should be at least 2 mm. The stretch ceiling must not rest directly on the loudspeaker.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e ✓ Design\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003eInvisible due to hidden installation \u003cbr\u003e\n\n\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e✓ Expandable\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003eUp to 3x \u003ca href=\"https:\/\/whd.de\/products\/sdl-400-s-silber?keyword=SDL%20400\" title=\"Spanndeckenlautsprecher_SDL400-S\" rel=\"noopener\" target=\"_blank\"\u003eSDL400-S\u003c\/a\u003e loudspeakers can be connected to the SDL 400-M.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e✓ Simple\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003eEasy handling \u0026amp;
